Application filed December 21, 1910. Serial No; 598,589.

To all whom it may concern Be it known that I, Gnome I-L TOMLIN- son, asubject of the King of England, re siding at Chicago, in the county ofCook and State of Illinois, have invented a certain new and uset'ulImprovement in the Apparatus for Feeding Materials to Digesters, ofwhich the following isa specification.

My invention relates to improvements in apparatus for feeding materialsto a digester, and is illustrated diagrammatically in one form in theaccompanying drawings, wherein- Figure 1 is a longitudinal sectionalview of the. apparatus; Fig. 2 is a section along the line 22 ot Fig. 1;Fig. 3 is a section along the line 3-3 of Fig. 1; Fig. 4 is a detailot'a modification.

Like parts are indicated by like letters throughout the several figures.

The belt conveyer. A. rides over the'pulley A in opposition to thescraper A which discharges onto the inclined weighing platform A. whichis supported at the edge near the pulley by the knife-edge A on thebracket A and at the edge farthest removed therefrom by'thc knife-edge Aand connecting link A which terminates at its upper end in the eye Acarried by the hook A and supporting spring A which is carried in thebracket A adjustable in position on the guide A".

The weighing platform A discharges :ti'ito the osjllating inclined trayB which is locate; within and supported from the chute B by means of thelinks B and which is oscillated by the link 13" and pulley B driven bythe belt 13" from the pulley A The chute B terminates at its lowerextremity in the funnel C and discharge pipe C in opposition to ll181'li{ll1ll0l6 C in the d'igester C and contains the; spraying nozzles Cin communication with the pipe C which is supplied from the reservoir0". The link A is carried on the knife-edge D on one end of the scalebeam D which is provided with the knife-edge D lin opposition to thebracket D.on the chute il and has the adjustable counterbalance weightD* and is in pivotal engagement. at one end with the piston rod l),piston, I) and dash pot D The tunnels E which are in opposition to thespray nozzles U and duachargc' by means of the flexible tubes E to thepipe E and reservoir C, are carried on the frame E which is supported atone end by the link E from the chute B and at the other end by the arm Ewhich projects from the fulcrum ot the scale beam D and arciso locatedalong the frame E that any downward movement of the frame will take themsuccessively out of opposition to the spraying nozzles v In themodification su gested in Fig. 4, I have shown the supply pipe Ccontrolled by the valve F which is operated by means of the lever'F andlink F from the arm E", It will be evident that 'while'I have shown inmy drawings an operative device still many changes might be made in thesize; shape and arrangement of the parts without departing materiallyfrom the spirit of my invention.

The use and operation of my invention are as follows :.As the beltconveyer operates, the material carried by it discharges upon theinclined weighing platform, and owing to its inclination passes acrossit in a continuous sheet being discharged upon the upper end of theoscillating inclined trr down which it travels to the funnel at theend'of the chute and thence through the pipe into the digester. Suitablemeans not shown force a continuous stream of acid or other liquidthrough the spray nozzles; this stream being discharged into the tunnelsin the position shown and. thence back to the supply reservoir. When thematerial is' passing across the weighing platform its weightdepressesthe platformv and raises the scale beamthus rotatingthe arnrwhichprojects from the beam. and thus carrying the tunnels back out ofregister witlf the spray nozzles so they discharge-onto the ma terialpassing along the traybelowa The arrangement issuch that one nozzleafter another comes into operation and for a slight quantity of materialonly a few of the nozzles will 0 erate'while for a large qua h titywhich greatly depresses the scale, all of the nozzles will. bebrought-into operation. The relation between the amount of-inate rialpassing and the amount of, acid discharged thereon is controlledbyauendjust 10'5 able spring and afco-unt'erbalanoe on the scale beam, thedash-pot being pIOVldGdlo;

prevent any violent changes in the supply owing to any localdisturbance' of. the

- amount ot'cellulose being discharged 'across the weighing plattorm.
